The default install of the MATE desktop installs too much I don't want.
Unfortunately the Debian installer does not allow coerces the
installation of "recommended" packages.
Therefore I did an install without *ANY* desktop environment.
[Used DVD1 of Debian 8.6, latest for which I had a physical DVD]
I then did
apt-get --no-install-recommends install mate-desktop-environment gparted
On reboot the desktop did not appear.
What is the forgotten command to automatically launch the desktop at boot?
TIA
